[Compose] Add spacing between Day composables in HorizontalCalendar without affecting container edges

[MarcLFJ]

Firstly, thank you for the excellent library! 🙏

Feature

While implementing a calendar, I encountered a problem with adding spacing between Day composables inside a HorizontalCalendar.

Current Behavior: Adding padding to individual Day composables results in uniform spacing, including the edges of the container (start and end of rows and top and bottom row).

Desired Behavior: I need the Day composables to be flush with the edges of the container, but with spacing between the individual dates.

Am i missing a feature or is this not possible as of right now? :)

Using the daysOfWeek() list, you can check if the CalendarDay.date.dayOfWeek is the first or last on the list and not apply the padding for those cases.

Thanks for the quick response. I can see i forgot to mention that i also only show a blank space for dates outside of the current month showing.

But your solution helped me find a way when also using day.position. I resorted to adding padding only to top and start and disabling when i was at the edges of the calendar.

Root container of the dayContent has the following applied to it's modifier:

Modifier
      .background(AppColor.Grey) // The color of the "border"
      .padding(
                      top = when {
                          day.position == DayPosition.OutDate -> spacing
                          day.position == DayPosition.InDate || isInFirstWeek -> 0.dp
                          else -> spacing
                      },
                      start = when {
                          day.position == DayPosition.InDate || isFirstDayOfWeek -> 0.dp
                          day.position == DayPosition.OutDate && date.dayOfMonth != 1 -> 0.dp
                          else -> spacing
                      },
                  )
      .background(AppColor.White)

Note: The DayPostion.InDate and DayPosition.OutDate is due to not showing dates from other months, but we still need to handle spacing for these, to have all "borders" aligned.
